Tyvek Non Standard Tyvex Gusset Envelopes Plain 381 x 254 x 51 mm Peel & Seal 55 gsm White Pack of 20

It’s not made of paper; it’s a smooth non-woven mesh of 100% high density polyethylene fibres. It has a swirling texture and a soft lustrous sheen. It feels as smooth as paper and as soft as fabric, whilst being stronger and more durable.

Tear, burst, puncture and water resistant, in fact virtually indestructible, it adapts to irregular shaped contents without losing any of its strength. Tyvek® envelopes offer unbeatable protection for your product samples, corporate literature, bulky gifts, promotional items, clothing, artwork and important documents.

Tyvek® is water resistant – water runs straight off it, without seeping in or weakening the material. The non-woven fibres of Tyvek® form a breathable, water and rot resistant layer that protects and keeps your contents dry, making it ideal for document storage and protection.

Plus it’s lightweight too, being up to three times lighter than paper or equivalent packaging materials. This delivers significant savings on postage and transport costs. All envelopes have a strong and secure peel and seal closure.

Make a responsible packaging choice; mailing packaging made from DupontTM Tyvek® can produce less waste, use less energy, and emit less CO2 than cardboard or low density polyethylene used in similar conditions. In fact, Tyvek® was the first European mailing product to ever achieve Carbon Trust product carbon footprint certification back in June 2010.

Expansion style for bulky mailings.
